BURNER ATTACHMENT FOR GAS-RANGES.

Specification of Letters Patent.

I To all whom. it may concern:

Be it known that I, Mnvnno A. Possons, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented-certain new and useful Improvements in Burner Attachments forGas-Ranges, of which the following is a. specification, reference beinghad therein to the accompanying drawing.

My invention relates to improvements in burner attachments for gasranges. a

The object of my invention is to provide a gas rangeof this character inwhich the oven burners and broiler burnervalves are so connected thatone cannot beturned on when the other is burning and vice versa, wherebyit is impossible to cause an explosion by filling the oven with gas fromone burner and igniting it by the other llghted' burner.

Another object of my invention-1s to provide a. simple, cheap andefiective attachment to accomplish the above result which can be readilyapplied to the ordinary gas range now in use.

In the accompanying drawing-Figure 1 is a perspective view of one cornerof a gas range showing my attachment applied thereto. Fig. 2 is anenlarged side elevation of my improved attachment. Fig. 3 is an edgeview of Fig. 2. Fig. 4 is an enlarged view of the lower end of theattachmentv showing the position of the connection rod in respect to thelower burner-valve when I the u per valve is open.

Re erring now to the drawings, 1 .re resents a as range, the oven 2 ofwhic is provided at its upper and lower ends with burners provided withvalves 3 and 4, for su plying as thereto. Heretofore these valves 3 an 4have been independently o erated and in such event when either of t eburners is in o eration and the other burner is turned on, t e ovenfills with gas and is ignited often causing a serious explosion. By myimproved attachment such an explosion cannot take lace as it isimpossible to turn on one of t e burners when the other burner is inoperation.

The valves 3 and 4, as heretofore described, control the gas to theupper and lower burners, one bem the baking burner and the other thebroi er, and are of the usual structure having the valve stems 5 and 6operated by the handles 6 and 7,

a which the valve stem 6 passes and stem 6; is

her 12, ,w

lower burner.

and which needs no further description, as the speclfic form of valveforms no part of my invention. The Valves 3- and 4 are arranged onedirectly above the other and the valve stem 5 of the upper valve isprovided with two outwardly extending ears 7 and 8, between which ispivoted by the cotter pin 9, a'rod 10 which extends downwardly. Thelower endfof said rod is provided with an enlarged "flat portion 11,which extends transverse the valve stem 6 and is provided with aninverted keyhole slot 11' through which I will now proceed to describe.The valve rovided with an elongated mem- 1ch is of a width to snugly fitwithin the elongated portion 13, of the keyhole-slot and of such alength that it can turn w1th1n the round lower end 14. of the keyholeslot, as shown in Fig. 2. The valve stem on each. side of the elongatedrectanlar-shaped member is provided with ob- 1 uely arranged ears 15 and16, which are a apted to extend out beyond the keyhole slot 11' and forma guide and support for the lower flat end 11 of the rod 10, whereby therod is supported. This arrangement of the ears prevents the necessity ofany addit1onal support for the rod. The valves 3 and 4 In Fig. 1, areboth shown closed and elther can be operated by the handle to open thesame for supplying gas to the upper or The opening of the lower valve 4.causes the rectangular-shaped member 12 to turn in a horizontal positionin the round opening 14 of the keyhole-slot and thus the upper valve 3being connected to the rod 10, cannot be opened as the member 12prevents the downward movement of the rod, thus it is impossible to turnon the upper burner when the lower burner is in operation. The turningon of the lower burner brin s the member 12 in a vertical position anthe upper valve can be operated, which forces the rod 10 down so thatthe member 12 is within the slot 13'. When the member 12 is within theslot 13, it will be seen that the lower valve stem 6 cannot Having thusdescribed my invention, what I claim'and desire to secure by LettersPatent is:

l. The combination with a gas range having upper and lower burners,valves for said burners having projecting valve stems, a rod having oneend connected eccentrically to one valve stem, the other end of the rodhaving a key-hole shaped opening embracing the other valve stem, thelast mentioned valve stem having a flat portion adapted to enter thenarrow portion. of the key-hole opening and loekedagainst turning,whereby the two valve stems are alternately locked so that both valvescannot be open at the same time for the purpose. described.

2. The combination with a gas range having an upper and a lower burner,a valve for each burner, an arm carried by the valve stem of one valve,a rod pivotally connected to said arm, an elongated member carried bythe valve stem of the other valve and the lower end of the rod having anenlarged portion provided with a key-hole slot adapted to receive thetransverse member carried by the valve stem whereby both valves cannotbe opened at the same time.

3. The combination with a gas range having an upper and a lower burner,a valve for each burner, the valve stem of one burner having anoutwardly extending arm, a rod pivoted to the said arm, the valve stemof the other burner having a transverse elongated member, ears carriedby the valve stem on each side of said member, the lower end of the rodhaving an enlarged flat portion provided with a key-hole slot to receivethe transverse member to fit between the ears of the valve stem, wherebythe rod is supported by the valve stem and both valves cannot be openedat the same time.

4. The combination with a gasrangehaving an upper and a lower burner, avalve for each burner, the stem of one valve having two outwardlyextending arms, a rod pivoted between said arms, the valve-stem of theother valve having a transverse elongated member, ears carried by thestem on each side of the said transverse member and arranged at an angleto said member, and the lower end of the rod having an enlarged flatportion fitting between the ears of the valve stem and having a key-holeslot adapted to receive the elongated transverse member whereby bothvalves cannot be opened at the same time, substantially as shown anddescribed.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses. I
